The over-arching theme of this work is that soil data affect the performance and realism of vegetation models with particular focus on their ability to predict or explain disturbances such as fire or disease. We tested the sensitivity of the Excel version of the 3-PG model to soil properties and...
This research focused on the experiences of 15 low income Mexican women immigrants participating in MAS and Superando, two family literacy programs at the center of these women's sociocultural change. This research sought to understand the extent to which participation in these two programs empowers women to create change in...
Expansion of Juniperus occidentalis into the sagebrush steppe has resulted in significant changes in understory composition. A consequence of increased J. occidentalis dominance may be a depletion of the seed bank. The potential for depletion is problematic because a reduction in the amount of species available from the seed bank...

During the summer of 1981, Oregon State University archaeologically tested three prehistoric sites on the William L. Finley National Wildlife Refuge. Among the sites tested were typical Willamette Valley floodplain and adjacent upland sites. Most settlement-subsistence pattern models proposed for the Willamette Valley have been generated with data from the...
The Pacific salmon market may often be characterized by
disequilibrium conditions and less than perfect information. Thus the
study of the decision-making behavior, especially short-run pricing,
of wholesale market participants in this industry requires the use of
alternative models to the conventional, price-taking, perfect
competition model of the firm.
This...
Daily evaporative flux and meteorological data from three sites were
collected and analyzed. Analysis included evaluation of several
reference evapotranspiration estimating methods which were theoretically
based on distinct physical laws. The estimating methods included pan
evaporation, energy-based Priestly-Taylor, and combination methods with
and without biological adjustments. The data set represented...
Technological advances in agricultural production over the past 40
years have contributed to the high standard of living enjoyed by many in
the United States. Extensive use of chemicals to enhance yield and
improve crop quality has played a major role in creating this highly
productive U.S. agricultural system. Increased...
Despite several decades of research developments, the survey-based contingent
valuation (CV) method remains one of the most controversial topics in environmental
economics. As the procedure matures and more applied studies are completed, there
is increasing pressure to make the results policy relevant. This research is composed
of three distinct yet...
